JAMES EDVARD MENDENHALL, OF SPRINGFIELD, OHIO, ASSIGNOR OF ONE- HALF TO SALATHIEL H. KNOX, OF SAME PLACE.

NIOWING-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 295,126, dated March 11, 1884.

` Application filed May 19, 1883. (No model.)

To all whom it may con/cern:

Be it known that I, JAMEs E. MENDENHALL, a citizen of the United States, residing at Springeld, in the county of Clarke and State of Ohio, have invented certain new and useful Improvements in blowing-Machines, and,

I do declare the following to be a'i'ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying draw-- ings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a top view ofthe machine. Fig. 2 is a longitudinal vertical section of the same, and Fig. 3 is a front elevation ofthe T-shaped arm.

This invention has relation to mowingmachines; and it consists in the construction and novel arrangement of devices, as will be hereinafter fully described, and particularly pointed out inthe appended claim.

Referring by letter to the accompanying drawings, u designates the frame of the mower, mounted on the .wheels b b, fixed to the axle c, which has its bearings in boxes d d in the side bars of the frame. The forward ends of the frame a are curved downward and forward, as shown, and to these ends the cutterbar and iinger-guards are connected in the usual manner. The sickle itself is provided withva cent-ral vertical stud, f, which is pivoted to the forward bentarm of the longitudinal rock-shaft g, which reciproeates the sickle when the mower'is in operation. The rockshaft has its bearingsin boxes h h on the crossbarswl f of the frame, and is arranged to convert the rotary motion of the gearing, through a T-lever secured to said .rock-shaft, into a Ver- tically-parallel cani-wheels k la', having starvpointed camteeth Z, beveled laterallyV from 4 their inner to their outer faces at their extreme points, as at m, are fixed to the axle c in such a manner that the point of each tooth of one of these earn-wheels is directly opposite the space between two of the teeth on the other Wheel. The T-shaped arm p, fixed to the rock-shaft between these two cam-wheels, has

arms o o', their lower surfaces being V-shaped in cross-section, corresponding to the shape of the spaces between the cani-teeth on the wheels 7c It. The under surfaces of these arms are also inclined downward toward theiroute'r 55 between 4the cam-wheels, at an angle of about 6@ ten degrees, so that the under bevel on one arm will rest on the point of the tooth on one cam-wheel, while the other under bevel will Abe between two of theteeth on the other cam- When the mover is moved, the rockshaft will be caused to rock, and will impart wheel.

a reciprocating motion to the sickle.

I am aware that it is not new, broadly, to provide a, harvester with two star-shaped wheels arranged upon its main axle, to communicate a vibratory motion to a lever connecting'with the cutting apparatus, the starwheels being so arranged upon the axle as to have the points in one relativelT opposite and in line with the spaces between the points on the other.

` Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

lThe combination, in a mowing-machine, of

the main drivingaxle, the cam-wheels secured thereon, and having star-pointed outwardbeveled cam-teeth, the rock-shaft, the T- shaped arm secured to said shaft, and having p arms inclined both vertically and transversely, 8 5

as described, and the cutter-bar, all substantially'as 'set forth.

In testi monY whereof I affix my signature in presence of two witnesses.

JAMES EDWARD MENDENHALL.
